f Be a knownjthat I, errantes H. NYE, 0f vitland in the county of Cumberland, and State of New Jersey, have invented new and useful Improvements in Detaching Ships Boat-s; and I do hereby declare that the following is a full, clear, and exact description tl1ereoi`,which-will enablet'hose skilled' in the art to make'and use the saine, reference being had tothe accompanying drawings, forming part ofy this specitication, in which- FigureI 1 is a longitudinal vertical section of a boat provided with` my detaching-apparatus, the section being taken through the line y y of g. 2.

Figure 2 is a cross-section of the same through the line x x, tig. 1. v

" t Similar letters of reference indicate corresponding The object of this in ventlon is to provide a simple and effective' means of detaching ships boats when suspended over the side ofthe vessel by davits or v The object of detaching-gear in general (and of which there is a number ot dit'erent kinds) is to detach both ends of a boat simultaneously from the davittackles, so that the. boat will fall into the Water `horizontally, and vinso falling, not be liable to be v swamped in a sea-way, or whenv the vessel is forging ahead.

My invention comprises certain improved features of construction, as herein set forth. l

In the drawi`ngs--' A- A is the boat, and y B B the chains or tackles,bywhich it is suspended from the davits.

1 These Vchains orvtackles connect with `the solid. metal shoulder-bolts a, which are claspedby the notched or recessed levers b; likewise ot'lmeta-l, against the heads of the ,metal stanchions e, being actuated to so Vclasp the said shoulder-bolts, by means of rods dconnecting their lower ends, and a lever, f, pivotedon afulcrumpin, at, passing through itand througlrtwc lug-plates,-

j, arranged on each side ot' the said` lever j; and affixed to the I'nidship thwart g, of `"the boat, as shown.-

thus keeping the levers b clasped upon the shoulder-` bolts' a, and for liberating the said `lever j, and thus allowing the leversb to be actuated back from the der-bolts is permitted, and the boat detached from the tackles B.

The stanchions c e arise fromv the keel oi' the boat, A

rlhis construction affords a solid resistance to the 4 action of the levers b, in clasping against the shoulder-bolts,

Near the pointwhere the plates It are joined to' the4 stanchions e, the said plates each separate into two plates, `o, which afford bearings for the pivot-pin p, of l their respective levers b, and. also form side-plates. to

kcepthe shoulder-bolts` from working out laterally from the clasp of the levers b.

The shonlder-bolts are formed tapering on one side,

, (that is, where they are claspedby the levers 1),) and straight on the other, where they, beartagainst the head ofthe stanchions, andthe tapering side terminates in a shoulder, on which the vnibs r, or-correspending shonlderof the notches in the levels b, catch.

The shoulders on the bolts (and the nibs) areA not at right angles to the vertical line of the tackles, but

inclined thereto, as shown, 'so that whether the boat lbe loaded heavy or light,the pbolts themselves will actuate the levers b backward from them when the said levers are left free to yield from the bolts, lby the liberation of the levery f.

The tripping-lever i', when holding the lever f, is seated in notches in the plates j, asshown,

Z lare rings formed on the shoulder-bolts a, to alibi-d a attachment for the tackle or chains B. l .A

l The outer ends of the rods d are forked to enclose the 'ends of the levers b, pivoted thereto, Aand one of these forks encloses, ,loosely,'one 'of the stanchions e, as shown. y

The peculiar excellenceof this detachinggear consists-v First, the small liability to wear ont andbecome inoperative.

Second, .the certainty of its properaction, whether the. boat is heavily or lightly loaded. Third, its simplicity and fewness of parts.

I will note that the rods d d are,.in practice, e nclosed by-tlie flooring 0f the boat, and Vthat the lever f sets backlinto' a notch or recess cnt in the thwart g, when the levers b are clasped upon the shoulder-bolts and are held in that position by the tripping-lever i, which is arranged across the notch.

In operating my invention, the boat is lowered nearly to the water, when the tripping-lever 'i is raised from its seat or notches, by any onevof the occupants ofthe boat. Both shoulder-bolts. then become simultaneously detached, and the boat falls into the water without disaster. shoulder-bolts, whereby` the escape of the said shoul- When the boat is to be hooked on and hoisted, theshoulder-bplts are inserted in place, and thelever f moved-to bring the leversb to clasp them, when the tripping-lever is then set to hold the lever f staby levers b are moved Simultaneously in the same dtouary. rect-ion, to lock `0r .unlock the bolts a, :Ls-herein de- I claim as new, and desire to secure by Letters scribed, for the purpose speciecl.
